21187499 Exhaust Pipe Elbow | Genuine Volvo Penta Part

🔧 Product Description

Genuine exhaust pipe elbow manufactured for the Volvo Penta exhaust installation that specifies part number 21187499. The elbow has application-specific flange orientation, bend angle and connection geometry.

⚙️ Key Features

• Genuine Volvo Penta exhaust elbow
• Factory bend angle and flange orientation
• Designed for exhaust temperature and vibration
• Maintains the original exhaust route
• Not interchangeable with 21187500 unless the catalogue specifies it

🔌 Function

The elbow redirects exhaust gas between connected pipe sections while maintaining a sealed high-temperature path.

⚠️ Common Signs of Failure

• Exhaust soot at a joint
• Cracking from heat or vibration
• Exhaust fumes in the engine compartment
• Misalignment of connected pipework

🛠️ Service Notes

• Renew the gaskets and seals at both joint faces and clean the faces back to bare metal; an exhaust joint will not seal on old gasket remains
• Look through the elbow before fitting and clear any carbon or scale, and where the elbow carries cooling water check its water passages for salt build-up and internal corrosion
• Check the flange faces for flatness and cracking, and check the studs and nuts — heat-cycled exhaust fasteners are often stretched or wasted and are best renewed
• Tighten evenly and progressively across the flange to the figure given in the workshop manual for your engine, then re-check once the engine has been hot and cooled again
• Where the elbow meets exhaust hose, use sound hose and the specified clamping arrangement, and keep the run rising and falling as designed so water cannot track back to the engine

📦 Condition
